The clinical results of 20 patients(20 eyes) who were operated due to perforated corneal laceration with traumatic cataract between March 5, 1991 and July 14, 1994 were analysed for the predictors of postoperative good visual outcome and compared simultaneous cataract surgery and implantation with secondary implantation. The most significant predictor of postoperative good visual outcome was the location of corneal laceration. Timing of lens implantation didn't influence significantly final visual acuity and postoperative inflammation. But postoperative complication were less frequent in patients where secondary IOL implantation was performed as opposed to those simultaneous IOL implantated.

Retinal dysplasia is an abnormal differentiation of the retina at embryonal retina stage with proliferation of its elements into rosettes, fold, and gliosis and it is very difficulat to distinguish between the various types of intraocular disease, especilaly retinoblastoma. We experienced a case of unilateral retinal dysplasia without systemic abnormalities occurring in a 5 months old boy. It was clinically suspected Retinoblastoma, which was proved to be Retinal Dysplasia by histopathologic examination.

PURPOSE: Malignant peripheral nerve sheath tumor without neurofibromatosis type 1 is very rare neoplasm. Development in the superficial soft tissue is exremely rare. Authors experienced one rare case of primary malignant peripheral nerve sheath tumor developed on abdomen. The clinical and histologic findings were described. METHODS: An 83-year-old man visited hospital with an 11x6.5x4.5 cm sized ulcerated and hemorrhagic mass on abdomen. The tumor was localized in abdominal skin and started growing 3 years ago. RESULTS: Wide excision with safety margin of 2cm and limberg flap was done. The postoperative biopsy revealed a malignant peripheral nerve sheath tumor. There was no evidence of recurrence of tumor for 16 months. CONCLUSION: Malignant peripheral nerve sheath tumor is an aggressive malignant tumor. An abrupt enlargement of size, ulceration and bleeding are suggestive of malignant chnages of the tumor. We recommand early wide excision with enough safety margin as treatment of malignant peripheral nerve sheath tumor.

BACKGROUND: The aim of surgical treatment for atrial septal defect is correction of anatomical and physiologic anomaly. Incidence of heart failure, cerebrovascular accident, atrial fibrillation and late mortality depend on the timing of surgery. Echocardiographic cardiac functional alteration after surgery is not surveyed sufficiently. So we intended to observe the alteration and function of cardiac anatomy after surgery. METHODS: We studied 22 patients who were undergone correction surgery of atrial septal defect at Keimyung university medical center. We devided patients into two groups according to age. Group I consists of patients who undergone surgery before 41 year old(mean age 32.25 year old, male 3, total 12). Group II comprises patients who undergone surgery after 41 year old(mean age 53.4 year old, male 1, total 10). We compared chief complaint, preoperative cardiac catheterization finding, pre- and post-operative echocardiographic finding(ejection fraction, end diastolic right and left ventricular dimension, grade of tricuspid regurgitation, paradoxical septal motion) between 2 groups. RESULTS: Preoperatively 6 patients(50%) of group I patients were diagnosed as mild congestive heart failure(according to NYHA functional class) and 2 patients(20%) of group II patients were in mild congestive heart failure. The Qp/Qs of both group were 3.5+/-1.7, 2.9+/-1.3, systolic right ventricular pressure were 42.1+/-10.5, 44.5+/-9.5mmHg, systolic pulmonary arterial pressure were 31.3+/-4.3, 36.6+/-7.3mmHg. 1 of group I patients and 2 of group II patients showed ejection fraction below 55% on postoperative echocardiography. The others showed normal ejection on echocardiography. Mean end diastolic right ventricular dimension was 3.84cm preopratively and 2.53cm postoperatively on group II patients. Mean end diastolic right ventricular dimension of group I patients was 3.94cm preoperatively and 2.81cm postoperatively. 3 of group I patients showed mild TR(tricuspid regurgitation), 5 showed moderate TR, and 4 showed severe TR preoperatively. 3 of group I patients showed loss of TR, 1 showed moderate TR, 8 showed mild TR. 3 of group II patients showed mild TR, 2 showed moderate TR, 5 showed severe TR preoperatively. 6 of group II patients showed mild TR, 3 showed moderate TR, 1 showed severe TR postoperatively. Paradoxical septal motion reflects right ventricular pressure overloading and was observed on both groups preoperatively. But after correction surgery, paradoxical septal motion persists at 6(50%) of group I patients, 6(60%) of group II patients. CONCLUSION: Conclusively, surgical correction for atrial septal defect before age of 41 is effective to prevent or slow down the manifestation of congestive heart failure, persistence of TR. Ejection fraction was improved significantly on echocardiography on both groups. But paradoxical septal motion persist after surgery, so more survey is needed.

PURPOSE: The purpose of this study was to integrate the results of qualitative studies to understand critical care survivors' experience of the post-intensive care syndrome (PICS).METHODS: This was a meta-synthesis of primary studies that used qualitative methods. We reviewed 26 qualitative studies on PICS selected from 8 international and Korean databases and from a manual search. Thomas and Harden's 3 stages (free coding, development of descriptive themes, generation of analytical themes) for thematic synthesis were utilized to analyze the collected qualitative data.RESULTS: Four descriptive themes emerged from the thematic synthesis: weak physical conditions, psycho-emotional changes, the painful-memory of intensive care units, and social vulnerability. The analytical theme for the current study was “unfamiliarity with the vulnerable self.” Critical care survivors had to confront entirely different “selves” after discharge from intensive care units. They had become physically weak, psychologically unstable, and the critical memories continued to create distress. These changes increased their social vulnerability by making them dependent on others, causing family conflicts, and changing interpersonal relationships.CONCLUSIONS: Finding from this qualitative synthesis and other related literature highlight the severity of PICS and the importance of rehabilitative intervention for critical care survivors.

PURPOSE: The treatment strategy for elderly patients older than 80 years with diffuse large B-cell lymphoma (DLBCL) has not been established because of poor treatment tolerability and lack of data. MATERIALS AND METHODS: This multicenter retrospective study was conducted to investigate clinical characteristics, treatment patterns and outcomes of patients older than 80 years who were diagnosed with DLBCL at 19 institutions in Korea between 2005 and 2016. RESULTS: A total of 194 patients were identified (median age, 83.3 years). Of these, 114 patients had an age-adjusted International Prognostic Index (aaIPI) score of 2-3 and 48 had a Charlson index score of 4 or more. R-CHOP was given in 124 cases, R-CVP in 13 cases, other chemotherapy in 17 cases, radiation alone in nine cases, and surgery alone in two cases. Twenty-nine patients did not undergo any treatment. The median number of chemotherapy cycles was three. Only 37 patients completed the planned treatment cycles. The overall response rate from 105 evaluable patients was 90.5% (complete response, 41.9%). Twentynine patients died due to treatment-related toxicities (TRT). Thirteen patients died due to TRT after the first cycle. Median overall survival was 14.0 months. The main causes of death were disease progression (30.8%) and TRT (27.1%). In multivariate analysis, overall survival was affected by aaIPI, hypoalbuminemia, elevated creatinine, and treatment. CONCLUSION: Age itself should not be a contraindication to treatment. However, since elderly patients show higher rates of TRT due to infection, careful monitoring and dose modification of chemotherapeutic agents is needed.

Background/Aims: We evaluated the feasibility and long-term efficacy of the combination of cytarabine, idarubicin, and all-trans retinoic acid (ATRA) for treating patients with newly diagnosed acute promyelocytic leukemia (APL). Methods: We included 87 patients with newly diagnosed acute myeloid leukemia and a t(15;17) or promyelocytic leukemia/retinoic acid receptor alpha (PML-RARα) mutation. Patients received 12 mg/m2/day idarubicin intravenously for 3 days and 100 mg/m2/day cytarabine for 7 days, plus 45 mg/m2/day ATRA. Clinical outcomes included complete remission (CR), relapse-free survival (RFS), overall survival (OS), and the secondary malignancy incidence during a 20-year follow-up. Results: The CR, 10-year RFS, and 10-year OS rates were 89.7%, 94.1%, and 73.8%, respectively, for all patients. The 10-year OS rate was 100% for patients that achieved CR. Subjects were classified according to the white blood cell (WBC) count in peripheral blood at diagnosis (low-risk, WBC < 10,000/mm3; high-risk, WBC ≥ 10,000/mm3). The low-risk group had significantly higher RFS and OS rates than the high-risk group, but the outcomes were not superior to the current standard treatment (arsenic trioxide plus ATRA). Toxicities were similar to those observed with anthracycline plus ATRA, and higher than those observed with arsenic trioxide plus ATRA. The secondary malignancy incidence after APL treatment was 2.7%, among the 75 patients that achieved CR, and 5.0% among the 40 patients that survived more than 5 years after the APL diagnosis. Conclusions Adding cytarabine to anthracycline plus ATRA was not inferior to anthracycline plus ATRA alone, but it was not comparable to arsenic trioxide plus ATRA. The probability of secondary malignancy was low.
